Black Bear Film Festival * October 20 â 22, 2017 * Milford, PA. âThe Black Bear Film Festival is one of the best festivals going on today. Our film, âMommyâs Box,â screened there and we were all treated like Hollywood stars. If you are a filmmaker this festival is a must.â.
PVC-U and PVC-M pressure pipes are suitable for use at service temperatures up to 50Â°C. For PVC-O pipes, the maximum continuous operating temperature should be limited to 45Â°C.
At temperatures above 20Â°C the maximum allowable operating pressure must be reduced in proportion to the material strength. Use of PVC pipes in the temperature range from 20Â°C up to the recommended maximum continuous operating temperature of 60Â°C is well defined (for more information see PVC Temperature Considerations).owever, it is not customary to utilise this increase in strength by increasing the pressure rating. The nominal pressure rating of the pipe at 20Â°C, or PN, should still define the maximum allowable operating pressure at lower temperatures.
